The initial conversion rate is 9.4013 shares per $1,000 principal amount, implying an initial conversion price of about $106.37 per share, subject to customary adjustments and potential increases after certain corporate events. Amkor also entered into Capped Call Transactions with a cap price initially at $139.50 per share, paying approximately $56.4 million to help offset dilution and cash outlays above principal on conversion. Initially, up to 16,487,435 shares may be issuable upon conversion based on the initial maximum conversion rate.

Amkor Technology’s largest shareholders, the Kim family and related trusts and entities, report beneficial ownership of 122,666,110 common shares, or about 49.38% of Amkor’s outstanding stock. This figure includes 550,000 shares that may be acquired through options exercisable within sixty days of May 1, 2026.

The ownership percentage is based on 247,872,518 Amkor shares outstanding as of April 21, 2026. The filing also details a new secured margin line of credit of up to $250 million from JPMorgan to Kim Capital Partners – KCP, LLC, backed by a pledge of 16,710,668 Amkor shares and guaranteed by Susan Y.

Amkor Technology, Inc. announced the pricing of a private offering of $1,000,000,000 aggregate principal amount of 0.00% convertible senior notes due 2031, guaranteed on a senior unsecured basis by certain subsidiaries. The company estimates net proceeds of about $981.7 million, or $1,129.0 million if the initial purchasers fully exercise their option to buy an additional $150,000,000 of notes.

Amkor plans to use $49.0 million of the net proceeds for capped call transactions and the remainder for general corporate purposes, including capital expenditures. The initial conversion rate is 9.4013 shares per $1,000 principal amount, implying an initial conversion price of about $106.37, a 52.5% premium to the $69.75 share price on April 30, 2026.

Amkor Technology, Inc. plans to offer $1,000,000,000 aggregate principal amount of convertible senior notes due 2031 in a private placement to qualified institutional buyers. The notes will be senior, unsecured obligations, fully and unconditionally guaranteed by certain subsidiaries that guarantee Amkor’s 5.875% senior notes due 2033.

Initial purchasers are expected to receive an option to buy up to an additional $150,000,000 of notes within 13 days of first issuance.

Amkor Technology reports strong Q1 2026 results, with net sales of $1.68 billion, up 27.5% from $1.32 billion a year earlier, and net income attributable to Amkor rising to $83.4 million from $21.1 million. Diluted EPS increased to $0.33 from $0.09.

Gross margin improved to 14.2% and operating margin to 6.0%, helped by higher factory utilization despite greater material content and higher overhead and compensation. Communications and automotive end markets grew particularly fast, at 42% and 28%. Operating cash flow rose sharply to $145.1 million, but heavy capital spending of $224.6 million on advanced packaging, test equipment and the new Arizona facility drove negative free cash flow of -$71.3 million. Amkor ended the quarter with $1.12 billion in cash and cash equivalents, $727.3 million in short-term investments and $1.41 billion of debt, while declaring cash dividends of $20.7 million.

Amkor Technology reported record first quarter 2026 net sales of $1.685 billion, up 27% from Q1 2025, driven by broad-based demand and strength in advanced packaging. Net income attributable to Amkor rose to $83 million, or $0.33 per diluted share, compared with $0.09 a year earlier.

Gross margin improved year-on-year to 14.2%, though it declined from 16.7% in Q4 2025, and operating income increased to $100 million. EBITDA reached $285 million. The company ended March 31, 2026 with $1.8 billion in total cash and short-term investments and $1.4 billion in total debt.
